The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI
functionality to the Linux operating system. ALSA has the following
significant features: Efficient support for all types of audio interfaces,
from consumer soundcards to professional multichannel audio interfaces,
fully modularized sound drivers, SMP and thread-safe design, user space
library (alsa-lib) to simplify application programming and provide higher
level functionality as well as support for the older OSS API, providing
binary compatibility for most OSS programs.
This package contains the ALSA /dev entries and basic development files.
